How about for 2021? 2022s have PCM6 that seem to have potentially solved some of the phantom battery draws - meaning that Bulletin #2229 does not apply to 2022s or those with PCM6.

We have someone who might be interested in doing this so maybe in the next couple weeks we can coordinate a test.

Sweet, would the 2021 part be the same (ground cable)? Please keep us posted.

@Antigravity I wanted to give a quick thanks for the time you’ve put into this. I don’t even on a 992 yet but hope to in the coming weeks. The potential for a.$2500 battery replacement is absurd and was definitely deterring me from getting RAS. . When you get this figured out, you will have earned a new loyal customer.😄

Putting aside the 'fear and loathing' aspects of this thread, curious from an electrical / chemical standpoint if an AGM battery will even work with a RAS setup? IOW is there some characteristic of RAS that requires an Li battery to be specified cars for cars equipped with RAS (eg discharge rates, etc)? Or is it soley an attempt to offset the additional weight or RAS components?

This has been discussed endless times. 991s used AGM with RAS, it's just that in addition to weight savings, it provides a more consistent punch over AGM.

Now about "fear and loathing" aspect you mention. If you talking in terms of the change of battery hurting anything.... well the change of a Ground Wires absolutely cannot hurt the existing Lithium Battery or the Car in anywaysince we are using a similar Battery and even putting a Lead/Acid Battery in there would not hurt anything. Also the Lin system that sends the data is a two wire system that carries voltage but is using the correct lin module and interface which will also not be at a different voltage. In the end either the Porsche Lithium Battery Sensor that is INSIDE the Porsche Lithium Battery will be sending Lin Data different than the Battery Sensor on the new Ground Cable so there will be a flag, or they will send relatively close data to eachother and there will be no flags. But no damage can occur by trying this because its lin data, using factory Porsche parts with the same exact Lin Connector that connects to both the Porsche Lithium Battery, and the Porsche Ground Cable. The unknown is if the same exact data is transfered using the same protocol when comparing what the Porsche Lithium Battery Sensor sends, and what the Porsche Intellegent Battery Sensor on the Ground Cable sends.... Last is being they will both be 2020 Parts for a 2020 system to read then it should manufactured the exact same simple for fact that Porsche does not want to mess around.... they want the guys who build these Cars to just be able to pop in a AGM Battery and its Ground Cable , or the Lithium Battery and its Ground cable. To much difference would cost way to much time and engineering cost.... or that is my theory I should say.

Sweet, thanks. Any pricing on it? I'm sure there must be changes to be applied to the VOF and ...?

Any update on this? Can we use the AGM cable with one of your batteries?
